Lighting57, they can be very destructive too. I've seen the results of their behaviors and it ain't pretty. The link I found doesn't say they're destructive and stink to hight heaven, at least not in so many words. I guess they can be good pets for some people but they're not a good idea for most people. I can see why someone with a ferret in a rental would be required to pay a huge pet deposit or fee. The downstairs neighbor was complaining about vet bills and health issues with her ferret, then replaced it with another when it died. To me that's a big go figure. I won't listen to her complain again.
